Without knowing what language you're using, anything about what your code looks like, nor what error is actually being reported by valgrind, about all that we can say is that you are probably trying to free an area of memory that you allocated at some point in the past and corrupted part of the region of memory that your memory allocation library uses to keep track of its memory pool OR you are trying to free memory that was never allocated.

Without more information, every assignment statement in your code is suspect, every return statement in your code is suspect, and every reference to every object that is a pointer in your code is suspect.

NAME
_nc_freeall _nc_free_and_exit - curses memory-leak checking SYNOPSIS
#include <curses.h> void _nc_freeall(void); void _nc_free_and_exit(int); DESCRIPTION
These functions are used to simplify analysis of memory leaks in the ncurses library. They are normally not available; they must be con- figured into the library at build time using the --disable-leaks option. That compiles-in code that frees memory that normally would not be freed. Any implementation of curses must not free the memory associated with a screen, since (even after calling endwin), it must be available for use in the next call to refresh. There are also chunks of memory held for performance reasons. That makes it hard to analyze curses ap- plications for memory leaks. To work around this, one can build a debugging version of the ncurses library which frees those chunks which it can, and provides these functions to free all of the memory allocated by the ncurses library. The _nc_free_and_exit function is the preferred one since some of the memory which is freed may be required for the application to continue running. Its parameter is the code to pass to the exit routine. RETURN VALUE
These functions do not return a value. PORTABILITY
These functions are not part of the XSI interface. SEE ALSO
